BACKGROUND Field of Invention

The invention disclosed relates to an exercise device, in particular, asliding grip resistance exercise device that can be used for but notlimited to: medial resistance pull-ups, lateral resistance pull-ups,chin-ups, lower back extension/sit-up assistance exercise.

While pull-up bars have long been revered in the fitness industry as ameans to work your biceps and upper back in a pull motion, these devicesoften neglect your triceps in a push motion and your lower back inextension exercises while also assisting you upright in a full motionsit-up. Also, pull-up bars work with vertical resistance, meaning anusers own body weight going up and down, vertical along with horizontalresistance allows a user to work their muscles in a more diverse way.This has left users to purchase multiple devices. There has yet to havebeen a device that will encompass all, until now.

Related Art

Prior art has consisted of pull-up bars with immobile hand grips thatdouble as a sit-up device; these devices hold the feet of the user flat,once the user is in a horizontal position, or descend back, there is noforce that will assist the user back into a vertical position, or ascendup. Prior art has also consisted of pull-up bars with sliding hand gripsthat do not offer adjustable medial or lateral resistance to work yourarms, upper and lower back, with the ability to manually lock hand-gripsin a preferred static position, invention disclosed solves that problem.As of now, U.S. Pat. No. 9,044,629 functions as a pull-up bar withsliding grip handles that doubles as a push-up bar with sliding handles.U. S. Pat. NO 20,120,115,683 functions as a pull-up bar with twoapertures along its frame, two handles protruding from apertures slidealong the course of its frame. Current device is disclosed as a pull-upbar, push-up bar, and shoulder press.

BRIEF SUMMARY

There is a need for a more versatile exercise device that will utilizemore muscle groups while exercising.

Disclosed fitness device will have at least six rubber pegs attached toits frame, rubber pegs will be utilized for wall and floor support. Thecavity of ventral bar supporting handgrips will have two springs, onespring for each respected handgrip. At the lateral ends of each springwill be spring caps, one spring cap will have a protuberance attached toit. The protuberance will allow one spring cap to rotate and compresssprings when engaged with handgrips appendage. The protuberance attachedto spring caps will also lock into “T” locks if the user would preferhandgrips to be static. Each spring cap protuberance will aid indifferent exercises depending on the location of spring cap withprotuberance, for example, the spring caps with a protuberance at thelateral ends of ventral bar will aid in compressing springs to performmedial sliding pull-ups, while the spring caps with a protuberance atmedial ends of ventral bar will compress springs to perform lateralsliding pull-ups or lower back extension/sit-up assistance exercises.

Tracks will be placed on top and bottom surface of bar to stabilize andguide hand grips. In another embodiment sliding function will be aidedby ball bearings, placed interiorly of handgrips. Also in anothervariation fitness device will have knobs to adjust resistance ofsprings. Aforementioned embodiments and variations can also be found inclaimed section of disclosure.

In another embodiment of disclosed invention, the user will be able toperform a lower back extension exercise with sit-up assistance. Byrotating rubber pegs attached to fitness device frame, for optimal floorand wall support. The user will place fitness device on the floorleaning it against a vertical support structure, attach lower backapparatus, and engage fitness device.

DETAILED DESCRIPTION

Detailed description will commence with the first variation of disclosedfitness device, this will entail: how parts are assembled, the processof making, and how one can use the fitness device disclosed. The firstvariation will be followed by the second variation of claimed fitnessdevice disclosed. The second variation will contain all utilitarianfunctions of first variation, with adjustable resistance. Also in thedetailed description portion, there will be references to certainfigures in different embodiments, to set forth how disclosed fitnessdevice can be constructed in many ways without departing from the natureand scope of disclosed fitness device.

First Variation

FIG. 1. Shows fitness device 101 in preferred embodiment. Horizontalbars 121, 119A-B, and ventral bar 117, are shown welded to curved bar105; in a different embodiment horizontal bars 121, 119A-B, and ventralbar 117 would connect to curved bar 105 by means of but not limited tobolts and nuts, for a more ergonomic way of packing fitness device 101.FIG. 2A-B shows fitness device 101 mounted on doorway 700 to be used forpull-up exercises. Rubber pegs 103-A will rest on door wall vertically,while rubber pegs 103B-C rest on door frame vertically (FIG. 2A-B). In adifferent embodiment ventral bar 117, may bend at its lateral ends, atan angle no greater than thirty degrees.

FIG. 3. Shows an exploded isometric view of fitness device 101. Rubberpegs 103-E will snap on horizontal bars 121, 119A-B, and ventral bar 117at their respected medial and lateral ends. Compression spring caps203B-C will reside in the cavity of ventral bar 117 at its medial end.One end of springs 201A-B will rest in compression spring caps 203B-C,while the other end of springs 201A-B will rest in compression springcaps 203-A, which will reside in ventral bar 117 lateral ends.

FIG. 9A-C shows how to lock components into the cavity of ventral bar117. User will push locking caps 113A-B and compression spring caps203-A thereby compressing springs 201A-B; before pushing locking caps113A-B fixtures 301A-B must be at a different angle than lockingfixtures 303-A (FIG. 9B), when fixtures 301A-B are anterior to lockingfixtures 303-A user will then rotate locking caps 113A-B until fixtures301A-B and locking fixtures 303-A are aligned (FIG. 9C), slowlydecompress spring by decreasing force applied to locking caps 113A-B,and let go (FIG. 9C). Handgrips 109-A can either be at ventral bar 117lateral or medial end to lock in components. In another embodimentrubber pegs 103D-E will be of the same width of rubber pegs 103-C. Also,in another embodiment locking caps 113A-B will be made from plastic.

FIG. 4A-B. Shows one embodiment of handgrips 109-A, in another claimedembodiment projections 503 and 501 which are used as a sliding mechanismfor hand grips 109-A will be replaced with ball bearings 861 (FIG. 27).Appendage 505 will have dual sides in order to make contact withprotuberance 601 (FIG. 6) from compression spring caps 203B and 203C forlateral sliding pull-ups (FIG. 8D-F), or lower back extension/sit-upassistance exercise (FIG. 15A-C);or appendage 505 will make contact withprotuberance 601 from compression spring caps 203 and 203A for medialsliding pull-ups (FIG. 8A-C). Each handgrip 109-A will have indentations111 to be used with lower back apparatus 817 (FIG. 16). Handgrips 109-Acan be made from metal or plastic and have rubber covering. Handgrips109-A will not be limited to cylindrical construct shown with discloseddrawings. Handgrips 109-A can be constructed to better conform to theuser of device, as long as it sticks to the spirit and scope ofdisclosure stated.

FIG. 5A-B. While a reference for compression spring cap 203 is onlynamed, the following description will also apply to compression springcaps 203-C since they are indistinguishable. FIG. 5A shows compressionspring cap 203 in different states, more specifically FIG. 5A shows anexplosive view of compression spring cap 203: concave spring cap 603will go inside spring cap with outer rim 205. Referring now to FIG. 5Bconcave spring cap 603 and outer rim spring cap 205 are combined to makecompression spring cap 203. Protuberance 601 of spring cap with outerrim 205 will be able to rotate independent of concave spring cap 603,rotation will be performed by means of appendage 505. (FIG. 10C, FIG.10E).

Referring back to FIG. 8A-F shows the practical use of fitness device101 in two different settings. To use for medial sliding pull-ups (FIG.8A-C), the user will start from a hanging position with handgrips 109-Apositioned at ventral bar 117 lateral ends, user will compress springs201A-B (FIG. 8B) (while still hanging) until fully compressed (FIG. 8C)and handgrips 109-A are at ventral bar 117 medial end, user will thendecompress springs 201A-B while lifting themselves up and creatingdistance between handgrips 109-A until handgrips 109-A are back atlateral starting position, this completes one repetition. In order toswitch from medial sliding pull-ups to lateral sliding pull-ups (FIG.8D-F), handgrips 109-A will have to be at the lateral ends of ventralbar 117, the user will then rotate handgrips 109-A up until projection503 is in between track 135 (FIG. 11A), and projection 501 is in betweentrack 131 (FIG. 12), then slide handgrips 109-A down ventral bar 117 tothe medial end of ventral bar 117 (FIG. 11B), rotate handgrips 109-Adown and perform exercise. To perform a lateral sliding pull-up (FIG.8D-F) hang from handgrips 109-A, slide handgrips 109-A down ventral bar117 compressing springs 201A-B, while doing this the user will belifting themselves up until springs 201A-B are fully compressed (FIG.8F) and handgrips 109-A are at ventral bar 117 lateral ends; user willthen decompress springs 201A-B by sliding handgrips 109-A medially downventral bar 117, while doing this the user will lower their body frompull-up position until springs 201A-B are fully decompressed andhandgrips 109-A are returned to medial position in relation to ventralbar 117, this completes one repetition. While the preferred execution ofperforming a medial sliding pull-up and lateral sliding pull-up has beendisclosed, it should be stated that the user can perform exercises in avariable of ways. Tracks 133, 135, 131, and 137 can be welded ontoventral bar 117.

The user will also be able to use fitness device 101 with statichandgrips for pull-up exercises, by locking handgrips 109-A in “T” lockapertures 127. FIG. 10A-E gives a close-up view of the process, FIG.10A-E also gives a close-up view of how fitness device 101 works fromthe perspective of handgrip 109 used in a medial sliding pull-upexercise. User of device will compress spring 201A which is carried outby appendage 505 pushing protuberance 601 medially down ventral bar 117(FIG. 10A-B). When compression spring cap 203 reaches the middle of “T”lock aperture 127 (FIG. 10B), the user will rotate handgrip 109 up (FIG.10C) decompress spring 201A by allowing it and handgrip 109 to travelhorizontally left until protuberance 601 makes contact with “T” lockaperture arm 125A (FIG. 10D); then rotate handgrip 109 down to lock in(FIG. 10E) and use fitness device 101 with immovable handgrips for amore traditional pull-up exercise. When fitness device 101 is used forlateral sliding pull-ups (FIG. 8D-F) and user wants to lock handgrips109-A into “T” lock apertures 127, they will use “T” lock aperture arm125B (FIG. 10-E).

Fitness device 101 has six “T” lock apertures 127, three for each sideof ventral bar 117, they will be distinctly placed so the user will getthe most benefit from location. For example, if handgrips 109-A werelocked in “T” lock apertures 127 on ventral bar 117 lateral ends theuser would perform a wide grip pull-up; if handgrips 109-A were lockedin middle “T” lock apertures 127 the user can perform either medium grippull-ups or chin-ups; and if handgrips 109-A were locked in medial “T”lock apertures 127 the user can perform either close grip pull-ups orclose grip chin-ups. FIG. 10A-E shows medial sliding pull-up with justone handgrip 109, left side of ventral bar 117, and components offitness device 101 inside cavity of ventral bar 117, it is my intentionto make clear that the use of fitness device 101 just outlined above andin FIG. 10A-E applies to both sides of ventral bar 117. In a differentembodiment, there will be an indication when handgrips 109-A are inposition to lock into “T” lock apertures 127, indication can be but notlimited to: markers that lie between “T” lock apertures 127, markers canequal or expand the width of handgrips 109-A to indicate when to rotate.

FIG. 14A-B shows clockwise rotation of rubber pegs 103-E. Depending onthe exercise the user is performing determines the setting of rubberpegs 103-E; for example, as stated earlier rubber pegs 103-C will standvertically to support hanging from door wall/frame (FIG. 2A-B). When theuser of fitness device 101 is performing lower back extension or sit-upassistance exercises (FIG. 15A-C) rubber pegs 103B-C will standvertically against door wall 800 and rubber pegs 103, 103A, 103D, and103E will sit horizontally on floor so that fitness device 101 iselevated from ground (FIG. 15A-C).

To perform lower back extension and sit-up assistance exercise.Handgrips 109-A must be in lateral sliding pull-up position (FIG. 8D-F),before placing fitness device 101 on the floor the user will adjustrubber pegs 103-E to make sure they are at the right setting, as statedin previous paragraph. The user will then place fitness device 101 onthe floor set against a vertical immovable structure, like a wall 800(15A-C). User will then connect lower back apparatus 817 by placinglower back connector 805-A into indentations 111-A, as shown in FIG. 16(lower back connector 805-A may snap into indentations 111-A; thisstatement is not meant to be limited in scope but to serve as an exampleof different embodiments of this invention that does not diverge fromthe spirit and scope of disclosed device). The user 809 will then sit onthe floor, place their upper or mid-back on cushion 801, feet should beplaced on the floor with arms behind your head or crossed on your chestfor a traditional setting, and legs bent (FIG. 15A-B). The user 809 willthen using only their upper back apply force to springs 201A-B causingthe user to descend and extend their lower back (FIG. 15C), once fullyextended the user 809 will ascend back to starting position with theassistance from springs 201A-B decompressing, and in doing so they areperforming an assisted sit-up. Lower back apparatus 817 may be made fromplastic or metal. In a different embodiment lower back apparatus 817will be height adjustable, this can be done but not limited to “X” bars803 constructed to become hollow cylindrical bars within another bar, sothat each bar will have two cylindrical bars within each other, andbelow pin 827 (FIG. 21) will be pinholes going down vertically on each“X” bar 803, a pin for each bar can be assigned, to adjust height pushpin into pinhole. Pin as well as cylindrical hollow bars may also be butnot limited to being spring-loaded. Also, there is a possibility whenuser is engaging lower back apparatus that handgrips 109-A can rotate upinto top “T” tracks (FIG. 11A-B) and bottom “T” tracks (FIG. 12) to dealwith this possible quandary in another embodiment device may come withone guardrail to prevent rotation. Guardrail may be but not limited to amold of top “T” tracks affixed to an elongated piece of metal or plasticwhich spans the vertical section of tracks 133 and 135 where theyconverge (FIG. 11A-B). A guardrail may not be included with device, butanother means to prevent rotation may come affixed to fitness device 101or lower back apparatus 817. Also, lower back apparatus 817 may beconstructed in a number of ways to those skilled in the art, but itsfunction will serve the purpose as stated in mentioned specification andclaims, this statement is not meant to limit the variable exercises onecan perform with device.

FIG. 17-22 shows different perspectives of lower back apparatus 817 andits components. FIG. 17 shows left hinge 807 fixed to lower backconnector 805 circled to detail the components of upcoming view. FIG. 18shows hinge 807 fixed to one “X” bar 803. Hinge 807-A (FIG. 21) allows abetter range of motion when lower back apparatus 817 descends (FIG. 15C)on a horizontal plane. FIG. 19 shows a back view of lower back apparatus817 with its sliding mechanism circled. FIG. 20 shows sliding mechanismwhen user is either performing lower back extension or assisted sit-upexercises (FIG. 15A-C); cylindrical bar 811 fixed to “X” bar 803 willslide down compartment 825A during ascension (FIG. 15C), on the rightside of “X” bar 803 the same movement is occurring in compartment 825B(FIG. 19). In another embodiment rollers or ball bearings may take theplace of cylindrical bar 811.

Second Variation

FIG. 23 shows a front view of second variation of fitness device 101. Ifyou refer back to FIG. 16 you will notice the only visual difference,besides the lower back apparatus 817, are knobs 829-A at each lateralend of ventral bar 117. Knobs 829-A will start out in a neutral position(no resistance added) (FIG. 33A-B), if the user would like to increaseresistance they will engage knobs 829-A by rotating them clockwise (FIG.33C-D) decreasing the diameter of springs 201A-B, in so doing increasingcompression resistance from springs 201A-B which the user will feel whenengaging device. When the user rotates knobs 829-A (FIG. 33C-D) in orderto engage resistance, circular gear protuberance 843 from circular gear841 will occupy one track of tracks 853-C (FIG. 33D), the user can theneither perform: a medial resistance pull-up (FIG. 8A-C) a lateralresistance pull-up (FIG. 8D-F) or a lower back extension/sit-upassistance resistance exercise (FIG. 15A-C). In order to decreaseresistance inclusive component 857 will have to return back to lateralends of ventral bar 117, once returned, key 833 will go into keyhole(FIG. 32) user will then rotate knobs 829-A accordingly. In order forsprings 201A-B to rotate, springs 201A-B will fit tightly into inclusivecomponents 857.

FIG. 24 shows the inner tracks 853-C for ventral bar 117, tracks 853-Cwill be placed parallel to one another and run from ventral bar 117lateral end to its medial end, on both sides of ventral bar 117. Tracks853-C can be metal, and may be welded onto ventral bar 117, but notlimited to that option. Tracks will not be limited to four.

FIG. 25 shows the posterior side of component 857. As in the firstvariation, there will be a total of four inclusive components 857, oneat each lateral end of springs 201A-B. Also as in the first variation,circular cap protuberance 847 will make contact with appendage 505 tocompress springs 201A-B (there is a difference in reference numbersbetween outer rim spring cap 205 (FIG. 5A) and circular cap 839 (FIG.26), because circular cap 839 has a circular aperture in its middle) toengage fitness device 101 for exercise or to lock in “T” locks 127 (FIG.10A-E).

FIG. 26 shows inclusive component 857 broken up. Circular gear 841 andspring gear cap 845 may be connected by screws 849 and bolts 851.Circular gear 841 rectangular feature will insert into spring gear cap845 rectangular feature and act in dual motion, meaning, when circularcap 839 is rotated do to circular cap protuberance 847 it will actindependently from circular gear 841 and spring gear cap 845. Referringback to FIG. 33D shows an example of the last statement: circular gearprotuberance 843 from circular gear 841 was rotated and circular capprotuberance 847 from circular cap 839 did not rotate. Spring gear cap845 key structure located in the middle of spring gear cap 845 (FIG. 26)may be a keyhole indentation or a keyhole aperture identical to circulargear 841 keyhole aperture (FIG. 26). In another embodiment circular cap839 and spring gear cap 845 can link, linking means can be but notlimited to spring gear cap 845 having a concave dome similar to concavespring cap 603 and inserted into circular cap 839. Spring gear cap 845would have circular gear protuberance 843 and serve the same utilitarianfunction as above disclosure mentioned, in this embodiment circular cap839 would still act independently from spring gear cap 845 when springgear cap 845 is rotated. Aforementioned statement is not meant to belimiting but to describe how disclosed fitness device can be configuredin a number of ways by those skilled in the art without departing fromthe scope and nature of disclosed fitness device.

Knobs 829-A will work independently of locking caps 113A-B, referring toFIG. 29-30 shows this process. FIG. 29 shows direction of where knob 829and its fixed cylindrical protuberance 831 will be inserted, which is acircular hollow aperture in the middle of locking cap 113A. Onceinserted circular ring 837 will either be tightened onto cylindricalprotuberance 831 or welded (FIG. 30), but are not limited to thoseoptions. Screw 835 may also secure key 833 to circular protuberance 831(FIG. 30), but is not limited to that option. FIG. 28A-B shows differentviews of knob 829 combined with locking cap 113A. FIG. 31 showscylindrical protuberance 831 direction of entry for key 833 into keyhole(FIG. 32).

The utilitarian ability of inclusive component 857 is accomplishedthrough its distinct key system, which can be designed in many ways tothose skilled in the art, but for intent and purposes, its function isthat of a key system, which is part of above disclosure. Also there aremany ways one skilled in the art can configure aforementioned fitnessdevice, for instance in the second variation: instead of circular gear841 having a rectangular feature and spring gear cap 845 havingindentations to link with rectangular feature, circular gear 841 canhave notches going along its frame and spring gear cap 845 can havenotches on its posterior side to link with circular gear notches, saidnotches will serve as a means to twist springs 201A-B when rotatedeliminating the need for tracks 853-C, instead, there will be one set oftracks for circular gear protuberance 843 to prevent rotation fromcircular gear 841 when engaged. In other words, this would eliminate theneed for multiple tracks to increase resistance inside ventral bar 117,but it would still serve the same utilitarian function of multipletracks. This statement is not meant to be limiting but to describe howabove mentioned disclosure can be configured in a number of ways tothose skilled in the art without departing from the spirit and scope ofclaimed fitness device.
